GAS-REGULATOR. FOR BURNERS.

"To all whm'n c Mm Be it known that I, Cnsnnnsli. Gurney, a, citizen rot the United States, anda resident of the city oi New.

' York,: (borough of Manhattan,) in the county and 'State of New York, haveinvented a new and Improved Gas-Regulator for Burners, ofwhich the following is a full, clear, and exact description.

{My invention relates particularly to gas regulators I nior-burners employed for heating and cooking purposes, and the object oi-the invention isto provide attachment to such a burner, whereby when a vessel or object to be heated is-placed over an opening inthe stoveabove the burner a full head of gas will be automatically supplied to said burner, and whereby further upon' the removal of such vessel or object will be automatically reduced to a greateror lesser extent .accordingto the set adjustment oithe device,

- the supply cockbeing meanwhile open.

,A iurther. purpose of the invention is to provide an attachment of the character described that will besimple, durable, economic and not liable to get out of order, and which may be attached to any style-oi heating or cooking burner.

The invention consists in the novel construction and combination of the several parts, as will be here- ,inafteriully. set forth and pointed out in the claims.

' Reference is to be had to the accompanying drawing iorminga part of this specification, in which is shown a longitudinal section through a burnerand a sectional .side' elevhtion oi the attachment appliedthereto.

' A repres'ents a gas supply pipe provided with the usualistopcock B and a mixing chamber B.

represents the body of an ordinary cooking or the body by means of a bolt 11, and 0 represents a supply. tube which is in communication with the body 0 aid the mixing chamber B, being provided with spiders '12 at points in its length.

, Where. the stop cock B 'enters the mixing chamber B',- it,s,out let is rendered more or less conical, as is shown at 13, to form a seat for a valve 16. The valve a needle valve and has sliding movement in said [spid e'rm-lg, the conical outer end of which valve is 1 adapted theeonical seat 13 provided ior it in the said stop cock B as is illustrated; and the said conical end of the valve is provided with grooves 14, so that some gas will always escape when the stop cock B is open. It, will be understood,:however, that any approved support may be provided for the said valve.

A three=armed lever D is lo 5 ted within the body C of the burner, being pivoted at he junction of its members on the connecting bolt 11 of said burner, or any convenient support; and thelarm ';or member 17 that extends upward and in direction oi the tube C, or at Specification of Letters Patent. Applicationfiled October 18, 1906. Saris-1N0. 839,486.

heatingburrier provided with the customary perforated crownl0, shown held above the upper portion of Patented July 16, 1907.

an angle to the two other arms of the lever, is providedwith a slot 19. .The outer end of the needle valve 16 is pivotally connected with said arm 17 by means of a pin 18' passed through the heel of said'valve and through the said slot 19 in the said lever arm 17 as is clearly shown.

The arm 20 of the lever D that normally extends downward and inward, is provided with a weight 21,

and the arm 22' of said lever that extends normally upward and outward is provided with a longitudinal slot 23, The lower end of a stem 24 is connected with v the lever arm 22 by means of a pin 24 passed through said stem-and the s1ot23 oi the lever arm r The stem 24 extends up through a central opening in the perforated crown 10 and is free to slide in said opening; and

at the upper endoi. said stem 24 a cap E is secured in any approved manner, as for example by providing the cap with a socket 25 into which the stem 24 enters. The'cap E is of less dimensions than the crown moi/(:8

upper face. Furthermore, said cap is provided with apertu'res so as to permit the passage of heat ironi the said burner through the said cap to the openingi i'n the stove beneath which said-cap is located. l

Normally the weight 21 of the lever D the burner'and is usually circular and convxed at;it s

'80 nthelower position shown by full lines, and the capE extends up through the opening in the stove; arid'at such time the needle valve 16 will have closed theoutlet oi the l the lever D is raised and the needle valve 16 is drawn from its seat '13, permitting a full supply of gas to be admitted to the burner. v

The amount of gas to be supplied to theburner when the attachment is in its normal position, is governed by means of a screw 26, or its equivalent, which is passed through the connecting bolt 11, or other support for the lever D, to an engagement with the weight 21, so that the weight 21 can be normally held more or less in an upper position, so as to normally permit more or less gas to escape from the gas pipeA when the burner is not in use. p

Having thus described my invention, I claim as new, and desire to secure by Letters Patent,

1. A gas burner. comprlslng afburner body, a mlxlng chamber, n stop cock connected with the mixing chamber the stop cock, snld needle valve hlngloosely plvdtcd to" one of the arms of the lever, a stem sliding in the crown of the burner and loosely pivoted to another ,arm of said lever, and a canyon the outer end of the stem.

L. A gas burner, comprising :1 'burner body, a mixing chamber, a stop cock connected witlr'the' mixing chamber and having a valve seat in its outlet, :1 tube connecting the mixing chamber withthe burner body, a three armed .pivoteii tolanother arm of said lever hyflr pin passing through the slot of the arm, and 'a cap on the upper end'of the stem. j

3. A gas burner, comprising a burner body, a mixing chamber having a valve seat in its-inlet, a tube connectingthe .mixing chamber with the burner body, a three nrmed lever. piyoted in the burner body, one of the arms being weighted, a needle valve having sliding and guided movement in the said tube and adapted to beseated in valve seat-ofthe mixing chamber, said valve .having grooves" in its-conical end and pivotallyconnected with one of the urine of the lever, a stem sliding in the crown of the burner body and having its inner end pivotally com nected with another arm 'of the said lever,,and a cap on the outer end of the stem.

4. A gas burner, comprising a burner proper, a valve mounted to slide in the burner and adapted to be seated in the gas supply for the burner, a three armed lever pivoted in the burner and with one arm of which the valve is loosely pivoted, a weight. carried by the second arm, a. stem sliding in the crown of the burner body and its inner end loosely pivoted to the third arm of the said lever, and a cap on the outer end of the stem.

5. In a gas burner for heating or cooking purposes, a needle valve slidably mounted and adapted to be seated in the gas supply pipe 1or vthe burner, n threearrn lever pivoted in said burner, a pivotal connection between one arm of the leverand said valve, 21 weight carried by the second arm of the lever below the valve, a' stern'pivotalIyc'on-a' nected with the third arm of the'lever and extending through the top of the burner, being capable of movement therein, and a cup at the outer end of the said stern.
